After some research, it turns out that the <line> entry says which line the
F appears on (as advertised), and that the clef is moved up or down so that
the 2 dots surround the line with the F. The Bass Clef is called a "F"
cleg, because the two dots surround the line which has the F on it.
The same works for Treble and "C" Clefs which can be moved up and down for
different instruments.
